Brevinema andersonii

''Brevinema andersonii'' (Brev. i. ne' ma. L. adj. brevis, short; Gr. n. nema, thread; N.L. neut. n. Brevinema, a short thread.) (an.derso'ni.i. N.L. gen. n. andersonii, of Anderson), named for John F. Anderson, who first described the organism.〔 This organism is a Gram-negative, microaerophilic, helical shaped, chemoorganotrophic organism from the genus ''Brevinema''.〔 ''Brevinema andersonii'' is host associated, strains have been isolated from blood and other tissues of short-tailed shrews (''Blarina brevicauda'') and white-footed mice (''Peromyscus Zeucopus'') and are infectious for laboratory mice and Syrian hamsters.〔〔''B. andersonii'' is readily identified by restriction enzyme analysis, and SDS-PAGE, or fatty acid composition data. Another identifier for ''B. andersonii'' is the sheathed periplasmic flagella in the 1-2-1 configuration. While cells are visible by dark-field or phase-contrast microscopy, they cannot be seen when bright-field microscopy is used.〔
== History ==
''Brevinema andersonii'' was first identified in 1987 by Anderson F. John, Russell C. Johnson, Louis A.Magnarell, Fred W. Hyde, and Theodore G Andreadis in blood and tissues from ''Blarina brevicauda'' (short-tailed shrew) and ''Peromyscus leucopus'' (white-footed mouse).〔 Initially thought to be associated with ''Borrelia burgdorferi'' this organism was finally brought to light with more advanced growth mediums. Upon electron microscopy of cultures from this medium, a distinct morphology stood out from the rest.〔 It was not until 1995 that a push for this organism to be found as a new species. This push came as a published article from the Journal of Systematic Bacteriology that exclaimed data supports this organism to be its own genus species. Written by D.L. Defosse, R. C. Johnson, B. J. Paster, F. E. Dewhirst, they found genomic evidence to support their claim that ''Brevienma andersonii'' was its own deep rooted spirochete. Their findings showed that this organism was around 75% similar in genome to other known spirochetes, this showed that ''B. andersonii'' was in a taxon of its own.〔
